Classification of robot sensors
According to the different detection objects, it can be divided into internal sensors and external sensors. Internal sensors are mainly used to detect the status of the robot itself (such as the angle between arms), and are mostly sensors for detecting position and angle.
External sensors are mainly used to detect the environment in which the robot is located (such as what object it is, how far it is from the object, etc.) and the condition (such as whether the object it grabs has slipped). Specifically, there are object recognition sensors, object detection sensors, proximity sensors, distance sensors, force sensors, auditory sensors, etc.
1. 2D visual sensor
The two-dimensional visual sensor is mainly a camera that can perform functions such as object motion detection and positioning. The two-dimensional visual sensor has been around for a long time, and many intelligent cameras can coordinate the action path of industrial robots and adjust their behavior based on the received information.
2. 3D visual sensor
Recently, 3D vision sensors have gradually emerged, and 3D vision systems must have two cameras shooting at different angles, so that the 3D model of the object can be detected and recognized. Compared to two-dimensional visual systems, three-dimensional sensors can more intuitively display things.
3. Force torque sensor
A force torque sensor is a sensor that allows robots to know the force and monitor the force on the robot arm. Based on data analysis, it provides guidance for the robot's subsequent behavior.
4. Collision detection sensor
The biggest requirement for industrial robots, especially collaborative robots, is safety. To create a safe working environment, it is necessary for robots to recognize what is unsafe. The use of a collision sensor allows the robot to understand what it has encountered and send a signal to pause or stop the robot's movement.
5. Safety sensors
Unlike the collision detection sensors above, using safety sensors can make industrial robots feel the presence of objects around them, and the presence of safety sensors can prevent robots from colliding with other objects.
6. Electromagnetic sensor
Modern magnetic rotation sensors mainly include four phase sensors and single-phase sensors. During the working process, the four phase differential rotation sensor uses one pair of detection units to achieve differential detection, and the other pair to achieve reverse differential detection. In this way, the detection capability of a four phase sensor is four times that of a single component. The single-phase rotation sensor with two components also has its own advantages, which is small and reliable, and has a large output signal, can detect low-speed motion, strong resistance to environmental impact and noise, and low cost. Therefore, single-phase sensors will also have a good market.
7. Fiber optic sensor
Fiber optic sensors are a new technology that has emerged in recent years, which can be used to measure various physical quantities, such as sound field, electric field, pressure, temperature, angular velocity, acceleration, etc. They can also complete measurement tasks that are difficult to achieve with existing measurement technologies. In narrow spaces, in environments with strong electromagnetic interference and high voltage, lightThe technology provided includes microprocessors, microcontrollers, sensors, analog integrated circuits, and connections. Some of the main applications and end markets of Freescale include automotive safety, hybrid and all electric vehicles, next-generation wireless infrastructure, intelligent energy management, portable medical devices, consumer electronics, and intelligent mobile devices. We have multiple design, research and development, manufacturing, and sales institutions worldwide.
In February 2015, Freescale and NXP reached a merger agreement, resulting in an overall market value of $40 billion.
